Mystical scanner problem

[Lordshooter]

If I connect a external HDD to a USB-port, unplug it later, because not used,
and if I use the same USB-port to plug in a scanner: Is that why my scanner possibly does not work?

(I am using a laptop.)

The scan program (Kooka) does enable printing via separate printer.
But it does not select any scan device: there is no such device there, from which to select.

The shell console gives this part of a output:
"found USB scanner (vendor=0x03f0 [hewlett packard], product=0x2305 [hp scanjet], chip=RTS8822L-01H) at libusb:001:003
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage."
and:
# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
# necessary."

Question: How do I run the program as root to find all devices?

Well, that is all for them moment. I hope someone helps me.

I would be very glad for some help/hints.

Thank you so much.

What's your distro? If it's Ubuntu or similar, type

sudo sane

and enter your password. Otherwise type

su -c sane

and enter the root password.

BTW a lot of USB scanners give trouble in Linux. Look in /usr/share/doc/libsane and with any luck you'll find a list of supported scanners.

Hello Hazel.

Output of "Run Command"...:

sudo: /etc/sudoers is mode 0646, should be 0440

Output of the Shell-Console:

alexander@6[~]$ su -c sane
Password:
bash: sane: command not found
alexander@6[~]$

alexander@10[~]$ sudo sane
sudo: /etc/sudoers is mode 0646, should be 0440
alexander@10[~]$ sudo sane





Root-Shell:

My OS is "SimplyMEPIS 6.5"


Thank you so much, dear Hazel,

Hello Hazel,

your BTW-tip, is not only interesting, it is fantastic.

I haven't reached the libsane file yet.

I am in here: /usr/share/doc/

This is a fantastic area.

I think, I have been i here a few times, but had forgotten about it again.

There is load of work here to do. I am just looking at a HP-file (my printer manufacturer) ...

So I shall give you a feedback soon.

This looks very good. Some more nitty-gritty work to do. Thanks.

See you later.

You seem not to have sane. Not to worry, you just have a different front-end to the libsane system. Sane is the command line front-end and most distros include it but perhaps Mepis doesn't. To run kooka as root, call up a konsole and type

su -c kooka

then give the root password. I suggest you also run scanimage -L as suggested.

The quickest way to find out if you have a program is often to use the which command. e.g. which sane. This works reliably if it is a command for ordinary users (stored in /bin or /usr/bin). If it is a housekeeping command stored in /sbin or /usr/sbin, which will find it if you are root, but not otherwise, because these directories are not on the user command path.

Hi Hazel,
thanks.

Here is my output from your suggestion:

Password:
root@9[~]# su -c kooka
kooka: cannot connect to X server

Hi Hazel,

something has suddenly happened with Kooka.

Instead of the stupid single windows, it shows a better an nicer window, all in one, something, like it used to be, before it got worse.

It just happened after giving in your command.

Here is screenshot:

Edit.
P.S..

Ah, now I see, what happened: It reset to the default configurations, and deleted all the files that where in the Gallery.

Lets see what happens next...
